Compared to many six-strut hexapod configurations, this five-strut design increases the ratio of working space to build volume while providing more residual stiffness at high swivel angles.
In addition to its 5-axis machining capability, this pentapod design can also swivel through ninety degrees. The machine controller, however, accepts conventional co-ordinate information supplied by a normal numerical control program. Bosch Rexroth MHS 40 direct drives with hollow-shaft motors raise and lower the spindles. Compared to toothed-belt systems, the direct drive gives a stiffer design with fewer parts, increasing reliability. As there is no belt, no retensioning is required. Machining applications for the pentapod include models for prototypes and forms for castings.

Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
